Chris, I've done this on several occasions when I wanted brighter whites,
or to clear out some brighter/whiter accents. A little tuft of cotton on
a sharpened stick can gently wipe away grunge.

I used just a long soak in water, as my experience was that adding alkali
or bleach was too crude -- the mark too obvious. A bleach solution, say 1
part bleach to 2 or 3 parts water, can be great for cleaning up messy
borders, however.

Note, BTW, that, if your color is archival, "bleaching" absolutely will
NOT lighten it. What bleach does is destroy gelatin, and can remove tone
by dissolving the gelatin size under it.
